For optimal performance, use Yamalube 4 10W-40 or an equivalent 4-stroke engine oil that meets or exceeds the specifications set by Yamaha.
It is recommended to change the oil every 100 hours of operation or every 6 months, whichever comes first.
Check the battery connections, ensure there is fuel in the tank, inspect the spark plug for wear or damage, and verify that the kill switch is in the "Run" position.
Regularly inspect brake pads for wear, check brake fluid levels, and ensure the brake lines are free of leaks and damage. Replace parts as necessary.
The recommended tire pressure is 12 psi for both front and rear tires to ensure optimal performance and safety.
Regular maintenance, such as keeping the air filter clean, ensuring proper tire pressure, and using the recommended grade of oil, can improve fuel efficiency.
Stop the vehicle immediately, allow the engine to cool, check coolant levels, inspect for radiator obstructions, and ensure the cooling fan is operational.
Locate the air filter housing, remove the cover, take out the old filter, and install a new filter. Ensure the new filter is seated properly before replacing the cover.
Use the adjustable preload on the shocks to modify the suspension settings. Turning the adjuster clockwise increases preload and stiffness, while counterclockwise decreases it.
Listen for clicking noises when turning, notice any vibrations during acceleration, and inspect for grease leakage around the CV boots.
